5.2 Transition

So with the PTR changes pretty much set and the death of the arcane spec as we currently know it how would you guys recommend we transition from a arcane mastery into a viable spec in 5.2? Many mages I know are specced mastery arcane and dont have a second set of gear to fall back on (Damn you enchanting!)

Well I at least can get around 8600 crit rating atm from my arcane gear, with just 1 item change, so its not that bad, but still am currently looking to ask my guild if I can change my loot prio to crit gear as we still got 2 full clears in EU..

Invocation nerf from 125% to 115% (by rule of thump 8 - 9% loss) and the lost FoF proccs from Pet Freeze hitting very hard. There is no 52% Frostbolt buff. There were 2 buffs to Frostbolt as i can remember:

24% damage dealt and 23% SP scaling buff, and 2 nerfs: 15% from Frostbolt debuff and another 10% from Invocation.

I don't know if its a tooltip change or w/e, but there is :

Frost

Frostbolt now deals 52% more damage, but its debuff no longer increases subsequent Frostbolt damage.

I wont change anything... Ofc I'll have to make some fixes in talents and glyphs but I'll keep playin' as a masetery Arcane.
Why?
Blizzard will not choose my spec. I always played as a arcane, I love that spec, and I wont change just because it's nerfed, it'll be buffed again soon cuz' blizzard is playin with us... Ooh, each patch, u change your way to play as a arcane and I like it.. Its like a challenge and Im in! On last patch of Cata I was doing more dps than a massive lot of fires, why cant I be decent on 5.2?
(sorry about my bad English, Im learning it)

"Natural" procrate is lower (approx 1,5 ppm), then we have 8 - 9% loss from invocation nerf and we lost 2 very important sources for mobile dps with scorch and freeze. Just imagine vizier zor'lok´s attenuation; you now only can spam Arcane Explosion and Fire Blast on CD.
